CSS to make the Classic Editor look more like the Block Editor

Modern Styles for the Classic Editor

Mark Root-Wiley, MRW Web Design

What

Even on sites that embrace the block editor, the Classic Editor screen may be used on post types that don't implement the post editor, such as a post type that relies heavily on ACF or similar plugins. These styles make the Classic Editor screen (without the editor) look more like the Block Editor screen.

Integration

For now, I'm not sure the best way to make integration easy, so I'm starting with a gist. Eventually this might turn into a full-blown repo. See faux-block-editor.php for one suggested implementation for how to use these.

To use these styles in a standalone plugin:

  1. Create a plugin folder called faux-block-styles and put the stylesheet and PHP file into them.
  2. Edit the plugin's PHP file to only target the post types you want.
  3. Activate and enjoy!

You might also choose to integrate these into an existing plugin or theme depending on how your site is build.

If this saved you an hour on a paid project…

You can buy me my next coffee or beer! 🍻

Contributions Welcome!

If you can make these styles better, get in touch with your suggestions.
